Refactor PD::Li Pools system, Upgrade PD::Pool and add better logging

- Add ResetFast to Pool using c++20 concept
- Add Put function to Pool
- Use Pool Index instead of pointers in Command
- Add accessor to Li Pools to prevent wrong command usage
- Add Command Formatter
- Use ResetFast for all Pools
- Add Reset func to Li::Vertex (for ResetFast)
- Add Pool Expandor and Put funcs to Lithium pools
- Add getters for GfxDriverBase to PD::Li Pools
